Our optimization study and benchmarks (all numbers are exact solver runs not surrogate prediction)

Norne field · 16 wells · 5 control intervals · 113,344 grid cells

Our best plan $3016.2M NPV in OPM Flow, +9.1 % vs Everest +65.1 % vs base plan (end of history)
Everest's best $2764.7M NPV in OPM Flow
NPV of our best plan vs Everest: The best NPV of each Everest start, and the plan the surrogate found without Flow, checked in OPM Flow. Every number is an OPM Flow run.

A new geology. Everest's best vs our best plan on another geological realization.
Trade-off plans: Plans that keep the best NPV and change the other objectives, checked in OPM Flow.
Trade-off plans. Plans that keep the best NPV and change the other objectives, checked in OPM Flow.
The optimization: The surrogate searches the controls without Flow; the curves are the field cumulative oil of every plan it tried, and the best plan's OPM Flow run.
